Since then, terminator as quite evolved, with plenty of new features that were highlighted in Terminator 0.9 beta 1 post.

It is now officially out with all those nifty features.

check out the changelogs:

terminator 0.9:
* Tab support
* Drag & Drop support
* Added support for ~/.config/terminator/config
* Switch the meanings of "horizontal" and "vertical" wrt splitting,
after extensive user feedback. Added context menu icons to try and
make the meaning clearer.
* Added keybindings for terms size and scrollbar manipulation. Thanks
Emmanuel Bretelle.
* Completely revamped config system which now transparently makes use
of gconf settings if they are available, falls back to sensible
defaults if not, and can be overridden entirely by ~/.config/terminator/config
* Support terminal zooming - now you can quickly hide all terminals apart
from one and either scale the fontsize or not.

* Watch the system monospace font setting. Closes LP #197960

* Try much harder to find a usable shell
